All across the country, a grassroots effort is taking place for GOP presidential candidate Ron Paul. "Sign bomb" events at busy intersections are going on and people are showing their support for the Texas congressman.

Ron Paul supporters were at the intersection of US-41 and Gladiolus Monday. And more supporters are doing the same thing all over the country – picking intersections and overpasses to show their support.

The grassroots effort started online and word spread quickly.

The so-called sign-bombers say the signs were homemade and were created at sign making parties.

They say the goal of this is to build Paul's support base throughout his campaign.

Of the 67 counties in Florida, 26 have the sign bomb events going on.

Ron Paul supporter Brian Harris says the congressman has an active support base and this shows the underdog still has a chance.

"One of the things that you'll commonly hear when you talk to people is, ‘Oh I love Dr. Paul. I love all of his positions, but I don't think he can win.' And we're out here today to show that he can win, if we do our part," Harris said.
